gain ALC880 provides 7.1 channels of outputs and multiple stereo inputs, along with flexible mixing, mute and

finer gain control functions to provide a complete integrated audio solution for PCs. Also the highest 192 KHz

sample rate DACs and Realtek proprietary hardware content protection are applicable for DVD audio, which only

implemented in high end consumer electronics, now is achieved by PCs with ALC880 inside. ALC880 is also the

one and only high definition audio codec integrating three pairs of stereo ADCs which can support microphone

array with AEC (Acoustic Echo Cancellation), BF (Beam Forming) and NS (Noise Suppression) technology

simultaneously to significantly improve recording quality for conference call. With this unique feature (3 pairs of

Stereo ADCs), ALC880 can perform the ultimate performance of HAD like using S/PDIF to output analog data or

multiple recording application.

• High performance DACs with 95 dB S/N ratio

• Meets performance requirements for audio on PC2001 systems

• 8 channels of DAC support 16/20/24-bit PCM format for 7.1 audio solution

• 3 stereo ADCs support 16/20-bit PCM format, two for microphone array, one for legacy mixer recording
